Hood enclosure assembly for cook-top downdraft ventilation

ABSTRACT

Embodiments of the present disclosure are directed towards a hood enclosure assembly for cook-top downdraft ventilation and associated systems, techniques, and configurations. In one embodiment, an apparatus includes one or more structural elements for placement on one or both of the cooking surface or a surface adjacent to the cooking surface that is substantially parallel with the cooking surface, the one or more structural elements being configured to form a cavity to house a vent of a downdraft ventilation system. Other embodiments may be described and/or claimed.

TECHNICAL FIELD

Embodiments of the present invention relate to ventilation and, in particular, to a hood enclosure assembly for cook-top downdraft ventilation and associated systems, techniques, and configurations.

BACKGROUND

Current cook-top downdraft ventilation systems may provide ineffective or inefficient ventilation of airborne cooking particles such as smoke, steam, grease or other particulate. In FIG. 1, an example prior art cook-top downdraft ventilation system 100 is depicted with a vent 104 disposed adjacent to a cooking surface 102. The vent 104 is generally configured to draw air 106 from surrounding ambient adjacent to the cooking surface 102. However, the vent 104 may not effectively or efficiently draw in airborne cooking particles 108 for a variety of reasons. For example, vent 104 suction may decrease based on a distance away from the vent 104, thus, suction may be insufficient to draw in airborne cooking particles 108 from a more distant region of the cooking surface 102. Such effect may be further exacerbated with an increased height of a cooking utensil 110 such as a pot or pan. In the prior art system 100, a structure 105 of the vent 104 may not effectively shield against turbulent airflow on sides and/or from behind the vent 104, which may increase turbulence of the airflow into the vent 104 from the cooking surface 102 and adversely affect ventilation.

Furthermore, the terms “comprising,” “including,” “having,” and the like, as used with respect to embodiments of the present invention, are synonymous.

FIG. 2 schematically illustrates an example cook-top downdraft ventilation system 200 (hereinafter “system 200”), in accordance with various embodiments of the invention. In some embodiments, the system 200 includes a vent 104, a cooking surface 102 disposed adjacent to the vent 104 and an enclosure assembly 250, as can be seen.

The vent 104 may be a downdraft vent. In some embodiments, the vent 104 includes at least a portion that is configured to draw air 106 (e.g., dashed arrows) in a downward direction (e.g., with a downward component towards a region below a height of the vent 104 or in a direction of gravitational force of the earth). For example, the vent 104 may be coupled with a duct that is configured to carry the air 106 downward away from the cooking surface 102.

In some embodiments, the vent 104 is a pop-up vent. The vent 104 may be configured to extend to a height above the cooking surface 102, as can be seen. For example, the structure 105 may be configured to move up to bring the vent 104 to a height above the cooking surface 102 to ventilate during cooking activity and to move down to bring the vent 104 to a level below the cooking surface 102 after cooking activity. In other embodiments, the vent 104 may be configured in other suitable configurations. For example, the vent 104 may be flush with the cooking surface 102 or flush with a surface 112 adjacent to the cooking surface 102. In some embodiments, the surface 112 may form a plane that is substantially parallel with the cooking surface 102.

The cooking surface 102 may include, for example, a surface of a cook-top stove, oven or range or other suitable cooking surface 102 that includes one or more heating elements for cooking. The heating element(s) may include, for example, burners 103 (e.g., gas or electric) or the like.

An enclosure assembly 250 may be disposed on one or both of the cooking surface 102 or the surface 112 adjacent to the cooking surface 102. Portions of the vent 104, structure 105 and cooking surface 102 are depicted in dashed form to indicate that such features are behind the enclosure assembly 250 in the view of FIG. 2. According to some embodiments, the enclosure assembly 250 may include one or more structural elements for placement on one or both of the cooking surface 102 or the surface 112 adjacent to the cooking surface 102. The one or more structural elements of the enclosure assembly 250 may include, for example, one or more components that form the back, top and sides of the enclosure assembly 250.

In some embodiments, the one or more structural elements of the enclosure assembly 250 may be configured to form a cavity 250 a to house the vent 104. That is, the vent 104 may be disposed within the cavity 250 a when the enclosure assembly 250 is positioned on one or both of the cooking surface 102 or the surface 112 adjacent to the cooking surface 102. According to some embodiments, the one or more structural elements of the enclosure assembly 250 may include a first side component (e.g., first side component 425 of FIGS. 4-5) configured to form a left side of the cavity 250 a, a second side component (e.g., second side component 435 of FIGS. 4-5) configured to form a right side of the cavity 250 a, a back component (e.g., back component 445 of FIGS. 4-5) configured to form a back side of the cavity 250 a and a top component (e.g., top component 455 of FIGS. 4-5) configured to form a top side of the cavity 250 a. In some embodiments, edges of the top component, the first side component and the second side component may be flush or substantially flush at a front side of the cavity 250 a that is disposed opposite to the back side of the cavity 250 a, as can be seen.

In other embodiments, the enclosure assembly 250 may include more or fewer components than depicted in FIGS. 4-5. In one embodiment, the enclosure assembly 250 may include any suitable combination of the components 425, 435, 445 and 455 of FIGS. 4-5. For example, two or more of the components 425, 435, 445 and 455 may be formed as part of a single continuous material structure (e.g., a single piece of metal). In other embodiments, two or more of the components 425, 435, 445 and 455 may be coupled in a removable fashion (e.g., using a screw, magnet or other removable fastening mechanism to temporarily hold the components together) or in a permanent fashion (e.g., welding or other permanent fastening mechanism). The enclosure assembly 250 may be composed of any of a wide variety of suitable materials including, for example, metal, polymer or ceramic materials, or combinations thereof. In some embodiments, the enclosure assembly 250 may be composed of stainless steel or a powder coated sheet metal.

In some embodiments, the enclosure assembly 250 may be configured for manual placement on one or both of the cooking surface 102 or the surface 112 adjacent to the cooking surface 102. The enclosure assembly 250 may have dimensions and weight that allow a person to position the enclosure assembly 250 over the vent 104 using only their hands. In some embodiments, the enclosure assembly 250 may be configured for manual removal from one or both of the cooking surface 102 or the surface 112 adjacent to the cooking surface 102. In such embodiments, the enclosure assembly 250 may be a portable, removable hood to facilitate ventilation when and where needed (e.g., during cooking activity). The one or more structural elements of the enclosure assembly 250 may be configured for disassembly (e.g., manual disassembly) in some embodiments. For example, components 425, 435, 445 and 455 of FIGS. 4-5 may be taken apart and/or may be collapsible to facilitate storage and/or cleaning of the enclosure assembly 250 when not in use. In some embodiments, the enclosure assembly 250 may be secured in position to house the vent 104 either temporarily or permanently using any suitable securing or fastening mechanism.

In some embodiments, the cavity 250 a formed by the enclosure assembly 250 is configured to extend over the vent 104 when placed on the cooking surface 102 and/or surface 112. In some embodiments, the cavity 250 a may extend over at least a portion of the cooking surface 102 when placed on the cooking surface 102 and/or surface 112.

The cavity 250 a formed by the enclosure assembly 250 may create an environment over the cooking surface 102 that increases ventilation of airborne cooking particles 108 such as steam, smoke, grease and the like through the vent 104 relative to the system 100 of FIG. 1. The enclosure assembly 250 may be designed or configured to direct inflow of air 106 towards the vent 104 from a region over the cooking surface 102. For example, suction of the vent 104 may create a low pressure region around the vent 104 and the enclosure assembly 250 may direct the low pressure region to an opening of the cavity 250 a facing the cooking area over the cooking surface 102. The directed low pressure region may increase air movement across the cooking area over the cooking surface 102 towards the vent 104. For example, the enclosure assembly 250 may direct suction of air 106 through the opening of the cavity 250 a in a region over the cooking surface 102 such that the air 106 primarily passes through the opening of the cavity 205 a, which may result in a more steady flow (e.g., increased laminarity or laminar flow) of the air 106 over the cooking surface 102 towards the vent 104 to increase a likelihood that airborne cooking particles 108, even at a distant region of the cooking surface 102, will be drawn into the vent 104. Additionally, a height of the opening of the cavity 250 a may provide, allow or create a pathway for currents of air 106 from a region above a height of the vent 104 towards the vent 104, which may increase a likelihood that airborne cooking particles 108 that are released at a height above the cooking surface 102 (e.g., at a height that is equal to or greater than a height of the vent 104) will be drawn into the vent 104. Extension of the top and side components of the enclosure assembly 250 over the vent 104 and the cooking surface 102 may increase effectiveness of suction from the vent 104 over the cooking surface 102.

In some embodiments, the back, top and side components of the enclosure assembly 250 may increase effectiveness of the vent 104 by shielding the vent 104 from interfering airflow (e.g., turbulent airflow) that may otherwise approach the vent 104 from the back, top and side directions. The enclosure assembly 250 may increase laminarity of air 106 flowing into the vent 104 over the cooking surface 102. In some embodiments, the enclosure assembly 250 may increase an efficiency of ventilating airborne cooking particles 108 through the vent 104 from ˜80% to 100% relative to the system 100 of FIG. 1.

FIG. 3 schematically illustrates a side view of an example cook-top downdraft ventilation system (e.g., the system 200 of FIG. 2), in accordance with various embodiments of the invention. As can be seen, the enclosure assembly 250 is configured such that air 106 and airborne cooking particles 108 are drawn towards the vent 104 through an opening of the enclosure assembly 250 that faces an area directly over the cooking surface 102. The vent 104 and a portion of structure 105 are depicted in dashed form to indicate that such features are disposed behind the enclosure assembly 250 in the view of FIG. 3. Further, some of the air 106 and airborne cooking particles 108 are depicted behind the enclosure assembly 250 in the view of FIG. 3 to show how they may be drawn towards the vent 104.

According to various embodiments, at least a portion of the enclosure assembly 250 may have a curved profile 250 b. For example, the top component and/or the back component of the enclosure assembly 250 may include a curved profile 250 b. The curved profile 250 b may enhance ventilation by reducing turbulence that may be associated with angled (e.g., rectangular) corners. The curved profile 250 b may increase a laminarity of air 106 currents within the enclosure assembly 250.

In some embodiments, a portion of the enclosure assembly 250 (e.g., portion of top component) may extend at least partially downward towards the opening of the enclosure assembly 250 from a position between the opening and a back component of the enclosure assembly 250, where the position has a greater height (e.g., height H2) relative to a height (e.g., height H1) of the enclosure assembly 250 at the opening. In other words, feature 250 c may slope down from a height H2 to height H1 of the enclosure assembly 250, as can be seen. The feature 250 c may increase efficiency of the ventilation using the enclosure assembly 250 relative to an enclosure assembly 250 that does not include the feature 250 c. In some embodiments, the height H1 may be a height of the enclosure assembly 250 at the front side of the cavity and the height H2 may be height at a position between the front side of the cavity and the back side of the cavity. The heights H1 and H2 may be relative to the cooking surface 102 and the height H1 may be less than the height H2. In some embodiments, the feature 250 c may have a profile that is linear or substantially linear, as can be seen. In other embodiments, the feature 250 c may have a profile that is non-linear.

The benefit of improved vent 104 efficiency using an enclosure assembly 250 with feature 250 c may result from changes of air 106 velocity and/or pressure according to Bernoulli's principle. For example, velocity and/or pressure changes for air 106 that passes over the feature 250 c may affect air flow through the opening of the enclosure assembly 250 in a way that increases efficiency of ventilation. The feature 250 c may be referred to as a “wing” or may additionally or alternatively be referred to as a “bevel” or “lid.”

In some embodiments, height H1 or height H2 may have a value from about 16 inches to about 20 inches. The heights H1, H2 may have other values in other embodiments. In some embodiments a height (e.g., H1 or H2) of the enclosure assembly 250 may be adjustable to accommodate varying heights of the cooking utensil 110 and/or vent 104 from the cooking surface 102. A height of the enclosure assembly 250 may be adjusted, for example, using any suitable mechanism such as, for example, coupling or decoupling an extension to the bottom of the enclosure assembly using temporary or permanent fastening mechanism, extending or retracting an extension portion that is slideably engaged with the enclosure assembly, folding or unfolding an extension that is coupled with the enclosure assembly using a hinge, and the like.

Various dimensions of the system 200 are depicted in FIG. 3. For example, in addition to the heights H1 and H2, a vertical distance h between a top edge of a cooking utensil 110 and an edge of the enclosure assembly 250 at the opening, a horizontal distance S between a far edge of the cooking utensil 110 and edge of the enclosure assembly 250 at the opening, and a depth W of the enclosure assembly 250 are depicted. A pressure P (e.g., lower pressure) created at the opening by the vent 104 is also depicted.

A relationship of the dimensional design of the system 200 is described in Equations [1] and [2]. For example, a maximum vertical distance h for the system 200 to provide ventilation of airborne cooking particles 108 may be defined by the relationship of Equation [1], where m is a mass of the airborne cooking particles 108, S is the horizontal distance between the far edge of the cooking utensil 110 and the edge of the enclosure assembly 250 at the opening of the cavity, F is a force of suction of the vent 104 (e.g., a vacuum level of the vent 104) and V_(g) is a vertical velocity of the airborne cooking particles 108.

$\begin{matrix} {h = {\sqrt{\frac{m \cdot s}{F}} \cdot V_{g}}} & \lbrack 1\rbrack \end{matrix}$

The vertical velocity V_(g) of the airborne cooking particles 108 may be directly or substantially proportional to a temperature T of the cooking utensil 110 and the force F of suction of the vent 104 may be directly or substantially proportional to a velocity V of air 106 through the vent 104. Accordingly, the relationship of Equation [1] may be rewritten as follows in Equation [2]:

$\begin{matrix} {h \propto {\sqrt{\frac{m \cdot s}{v}} \cdot T}} & \lbrack 2\rbrack \end{matrix}$

In some embodiments, the discrete parts of the enclosure assembly 250 may be manually assembled by a user of the enclosure assembly 250. In some embodiments, the side components 425 and 435 may include extensions, as can be seen, for fastening of the top component 455 and/or back component 445 using, for example, screws or magnets, or combinations thereof.

In other embodiments, the enclosure assembly 250 may include more or fewer components than depicted in FIG. 5. In one embodiment, the enclosure assembly 250 may include any suitable combination of the components 425, 435, 445 and 455. For example, two or more of the components 425, 435, 445 and 455 may be formed as part of a single continuous material structure (e.g., a single piece of metal). In other embodiments, two or more of the components 425, 435, 445 and 455 may be coupled in a removable fashion (e.g., using a magnet or removable fastening mechanism to temporarily hold the components together) or in a permanent fashion (e.g., welding or permanent fastening mechanism).

The structural elements may be coupled together using any of a variety of suitable techniques such as, for example, temporary techniques (e.g., magnets, screws and the like) or permanent techniques (e.g., welding), or combinations thereof. Subsequent to fabricating the one or more structural elements at 904 and/or coupling together two or more of the structural elements, the structural elements of the enclosure assembly may be assembled and/or sold to a user of a downdraft ventilation system for assembly and use.

FIG. 10 is a flow diagram of an example method 1000 of using a hood enclosure assembly (e.g., enclosure assembly 250 of FIGS. 2-6), in accordance with various embodiments of the invention. The method 1000 may comport with techniques described in connection with FIGS. 2-6 in some embodiments.

At 1002, the method 1000 may include receiving one or more components of a hood enclosure assembly. The components may include, for example, components 425, 435, 445 or 455 of FIGS. 4-5. For example, a user of the enclosure assembly may receive the one or more components from a manufacturer or seller.

At 1004, the method 1000 may include assembling the hood enclosure assembly to form a cavity (e.g., cavity 250 a of FIGS. 2, 4) to house a vent (e.g., vent 104 of FIGS. 2, 3) of a downdraft ventilation system (e.g., system 200 of FIG. 2). The hood enclosure assembly may be assembled, for example, by using any suitable fastening mechanisms including, for example, temporary or permanent mechanisms. Assembling may include, for example, coupling together two or more of the components 425, 435, 445 or 455 of FIGS. 4-5 using screws, magnets, insert features, or other suitable fastening mechanism. In other embodiments, assembling may include extending hinged components away from one another to provide a cavity space. Other suitable techniques to assemble the hood enclosure assembly may be used in other embodiments.

At 1006, the method 1000 may include placing the hood enclosure assembly on or adjacent to a cooking surface (e.g., cooking surface 102 of FIGS. 2-3). The hood enclosure assembly may be configured for manual placement on the cooking surface and/or a surface (e.g., surface 112 of FIG. 2) that is adjacent to the cooking surface. When placed, the cavity may be configured to extend over the vent and/or over at least a portion of the cooking surface. In some embodiments, the enclosure assembly may be permanently fastened to the cooking surface or the adjacent surface. In other embodiments, the enclosure assembly may be temporarily placed on the cooking surface (e.g., when needed for cooking). Guides for placement of the hood enclosure assembly may be used. For example, a base structure with marks or grooves to receive edges of the hood enclosure assembly may be disposed on the cooking surface and/or the adjacent surface in some embodiments.

At 1008, the method 1000 may include removing the hood enclosure assembly from the cooking surface or an adjacent surface. In some embodiments, the hood enclosure assembly may be manually removed from the cooking surface and/or the adjacent surface.

At 1010, the method 1000 may include disassembling the hood enclosure assembly for storage. In some embodiments, removing the hood enclosure assembly at 1008 may include one or more actions of disassembling the hood enclosure assembly for storage at 1010. In other embodiments, the hood enclosure assembly may be removed and then disassembled. In an embodiment, disassembly may be performed manually and without the use of an additional tool.
